RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION.

ATTENTION INSTALLING PERSONNEL

As a professional installer you have an obligation to know the product better than the customer.  This includes all

safety precautions and related items.

Prior to actual installation, thoroughly familiarize yourself with this Instruction Manual. Pay special attention to all

safety warnings. Often during installation or repair it is possible to place yourself in a position which is more hazardous

than when the unit is in operation.

Remember, it is 

your 

responsibility to install the product safely and to know it well enough to be able to instruct a

customer in its safe use.

Safety is a matter of common sense...a matter of thinking before acting. Most dealers have a list of specific good

safety practices...follow them.

The precautions listed in this Installation Manual are intended as supplemental to existing practices.   However, if there

is a direct conflict between existing practices and the content of this manual, the precautions listed here take

precedence.

*NOTE:  Please contact your distributor or our website for the applicable product data book referred to in this manual.
